  2. Agenda • Web design • HTML • JavaScript • PHP • XML • AJAX

  3. What is Web design? • Web design is the skill of designing presentations of content that is delivered to an end-user through the World Wide Web, by the way of a browser • Languages that are used for the purpose of web designing are called Web Languages

  4. Web designing languages • Markup languages- HTML and XML • Style sheet languages- CSS and XSL • Client-side scripting- JavaScript and VBScript • Server-side scripting- PHP and ASP • Multimedia technologies- Flash and Silverlight

  5. HTML • HyperText Markup Language • Used to design Web Pages • Is a text and image formatting language used by internet browsers • Is written in the form of "tags" that are surrounded by angle brackets • Plain text editor like NOTEPAD can be used to edit HTML • Professional developers prefer HTML editors like FrontPage or Dreamweaver • Don’t need any Web server or Website to view HTML file • To publish your work, you must save your pages on a web server. • IIS or PWS turns your computer into a web server. • IIS comes with Windows 2000, XP, Vista and NT • PWS is outdated now for professional use

  6. HTML Elements • <HTML> • <HEAD> </HEAD> • <BODY> …</BODY> • </HTML> • <P>This is a paragraph</P> • <Ahref="http://www.google.com">This is a link</A> • <imgsrc=“nisha.jpg" width="104" height="142" /> • <TABLE> • <TR> • <TD> Cell 1</TD> • </TR> • </TABLE>

  7. JavaScript • Official name is ECMAScript • Scripting language • Designed to add interactivity to HTML pages • Case sensitive • Embedded directly into HTML pages • Interpreted language • Everyone can use JavaScript without purchasing a license • Can react to events • Can be used to validate data before submitted to the Server • Can be used to detect Visitor’s browser • Can be used to create Cookies • JavaScript in the body section will be executed WHILE the page loads • JavaScript in the head section will be executed when CALLED

  8. JavaScript Statements • <script type="text/javascript"> document.write("<h1>This is a heading</h1>"); </script> • if (condition) { document.write("<b>Good morning</b>"); } • switch (n) { case1: …….. } • for (var=startvalue;var<=endvalue;var=var+increment){code to be executed} • Many other statements like while loop, exception catching, boolean expression and validations are possible

  9. PHP • PHP: Hypertext Preprocessor • Server-side scripting language, like ASP • Scripts are executed on the server • Supports many databases like (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) • Open Source software • File extensions are ‘.php’, ‘.php3’ or ‘.phtml’ • PHP runs on different platforms (Windows, Linux, Unix, etc.) • PHP is compatible with almost all servers used today (Apache, IIS, etc.) • PHP is FREE to download from the official PHP resource: www.php.net • PHP is easy to learn and runs efficiently on the server side

  10. PHP statements • A PHP scripting block always starts with <?php and ends with ?>. • A PHP scripting block can be placed anywhere in the document. • PHP automatically converts the variable to the correct data type, depending on its value • Just like ASP it uses Variables, Strings, Operators, IF.. Else, Switch, For Loops, Functions, Forms, Arrays

  11. XML • EXtensible Markup Language • Designed to transport data and not display data • Tags are not predefined. User can define Tags. • Self descriptive • Used to create new languages like XHTML, WSDL, WAP • Simplifies data sharing and data transport • XML documents form a Tree structure • XML parser can be used to convert XML to JavaScript

  12. AJAX • Asynchronous JavaScript and XML • a new technique for creating better, faster, and more interactive web applications. • a JavaScript can trade data with a web server, without reloading the page. • Based on HTML, JavaScript, XML & CSS • It is browser and platform independent • Google suggests to use AJAX

  13. Conclusion • Enhances business development e.g. some of internet shopping websites like ebay.com, yatego.com • Safe money transactions are possible over internet through internet banking • Internet marketing possible • E-commerce empowers • Effective communication • Replaces email and newsletters • Less time searching and hunting for commonly needed information • Fast and easy access to website content from one place
